Axelar

Architecture

Axelar constitutes a universal interoperability network, designed to connect diverse blockchain ecosystems through a decentralized network of gateways. Its core function centers on facilitating secure cross-chain communication and asset transfer, addressing fragmentation within the Web3 landscape. The protocol employs a Cosmos-SDK based architecture coupled with a novel interchain communication protocol, enabling generalized message passing between chains without requiring bespoke integrations. This design prioritizes scalability and composability, allowing developers to build applications spanning multiple blockchains with relative ease, and reducing reliance on centralized intermediaries.
